Title: Anti-noise curves
IPC: E01F8/00
Filed: 1992-12-11
Abstract: The anti-noise curves are prismatic or cylindrical acoustic barriers of vertical generatrix, following curved lines of variable radius which can be optimized in accordance with the sound source and the level of protection it is desired to give to the environment. The anti-noise curves may be installed on roads, motorways, railways, airports, industrial or sports zones. As a consequence of their shape, they require no foundations, since they are stable, and can absorb the impact of vehicles, moving slightly. They can easily be put back into the initial location. The anti-noise curves were designed so as to allow the planting of trees and shrubs in their own axis of development so as to guarantee better absorption and deflection of noise, presenting a corrugated appearance with good environmental and acoustic effect. <IMAGE>

Abstract: FIELD: pumping liquids out of deep wells. SUBSTANCE: flexible diaphragm forms cavities for actuating medium and liquid to be pumped out. Cavities are formed by one or several chambers arranged inside pump casing between end walls of the casing. Cavities for liquid to be pumped out are in free communication with casing; they are part of this casing and are brought in communication with source of medium to be pumped out through suction valve; they are also in communication with discharge passage through delivery valve. Actuating medium (liquid) cavities are brought into communication with its source by means of respective branch pipes located in casing and actuating medium passage. Hydraulic motor located on ground or directly above the pump in tubing may be used as actuating medium source. Flexible diaphragms may be shaped to form of surface of chamber wall forming the respective chamber when pressure in other chamber exceeds that in first one by no more than 10 percent of maximum working pressure differential. Cavities for medium to be pumped out are brought in communication with its source and with passage for its discharge in turn. To this end, pressure in actuating medium cavities is changed cyclically at supply and discharge of medium. Position and shape of flexible diaphragms in chambers are changed cyclically as well. In each cycle of above-mentioned changes, volume of actuating medium fed to respective cavities is kept lesser than difference between maximum and minimum volumes of cavities for medium to be pumped out at any extreme position of flexible diaphragms. EFFECT: increased overhaul period for pump; enhanced maintainability of pumps and extended range of medium being handled.

Abstract: FIELD: optics, eye protection systems. SUBSTANCE: given invention can be used to protect driver's eyes from blinding with light of head-lights of opposite road transport. In agreement with invention luminous flux is attenuated in aperture angle corresponding to size of pupil thanks to local attenuation. Proposed method in contrast to known one of protection of driver's eyes from blinding by head-lights of opposite road transport leads to attenuation of luminous flux in aperture angle 0.08-1.0 deg formed by eye's pupil and each head-light. Attenuation may be achieved by way of absorption of luminous flux. Result can be also achieved when luminous flux is attenuated by reflection or by refraction. Attenuation of light in aperture angle corresponding to size of pupil does not practically change illuminance of background which improves observation conditions. EFFECT: increased efficiency of protection of eyes from blinding with bright source of light, specifically of driver's eyes from luminous flux of head-lights of opposite road transport.
